Abstract
WHEN
People write abstracts when they need to:
  • submit articles to journals, especially online journals
  • write a proposal for a conference paper
  • apply for research grants
  • complete their M.A. thesis or Ph.D. dissertation

WHY
Abstracts allow readers to preview the contents of a paper to quickly decide whether it is worth their time to read it.

WHAT
An abstract is a self-contained but concise summary of a longer piece of writing. Abstracts are typically 150 to 250 words and follow set pattern:
  • State main objectives. (What did you investigate? Why?)
  • Describe methods. (What did you do?)
  • Summarize the most important results. (What did you find out?)
  • State major conclusions and significance. (What do your results mean? So what?)

HOW
To write an effective abstract one should:
  • write it as a single unified paragraph
  • make it intelligible to a wide audience
  • be concise: rephrase rather than quote
  • vary sentence structure
  • provide logical connections between the information included
  • use non-evaluative language: report instead of comment
  • include key words that quickly identify the focus of the original work
  • not use technical jargon unless it is clearly defined
  • use digits for numbers except when beginning a sentence
  • use past tense for the work done and present for conclusions and current applications
  • use active verbs rather than passive whenever possible
  • avoid using personal pronouns
  • not refer to information that is not in the original work
  • not include references to figures, tables, or sources
